The standard spacing between steel bars in a concrete slab typically ranges from 12 to 18 inches, depending on the specific design requirements and load conditions. For residential applications, a common spacing is 16 inches on center. However, factors such as slab thickness, intended use, and local building codes can influence these dimensions. Always consult structural engineering guidelines or local regulations for precise specifications.
Steel reinforced concrete is concrete with rods of steel running through it.
structual steel is the widw flange column's and beam's as well as plate steel angle iron ect.. it falls under aws D1.1 welding code. reinforcement steel/reinforcing steel is the rebar, dba,(deformed bar anchor), hsa, (headed stud anchor) that is placed in concrete, floors, walls, footings, ect... it falls under aws D1.4 welding code
Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
In reinforced concrete construction, the modular ratio refers to the modulus of elasticity of concrete to that of steel. It is used in structural design calculations to determine distribution of stresses between concrete and steel in beams and columns.
because concrete is unpredictable than steel
Steel reinforced concrete is concrete with rods of steel running through it.
No, it is not recommended to pour concrete directly onto steel bars painted with red oxide primer. The primer may prevent proper adhesion between the concrete and the steel, leading to a weaker bond and potential structural issues. It is important to remove any paint or primer from the steel bars before pouring concrete to ensure a strong and durable connection between the two materials.
The steel rods are there to strengthen the concrete - making it reinforced concrete.

Concrete is much more fire resistant. This is shown by the design of reinforced concrete structure where the steel is placed within the concrete. A major reason is that the concrete protects the steel from any fire. Steel only construction requires the steel to be covered in a fire protection material.
Steel expands when heated because the heat causes the atoms within the steel to vibrate more, increasing the spacing between them. This expansion can be measured in terms of thermal expansion coefficients.

Mainly re-enforced concrete (concrete that's been set around steel rods). The cables are made from many long strands of steel.
